|
Pitch |
The plane nose goes up or down. The pilot adjusts the elevators by pushing the wheel in or out. |
|
|
Roll |
The plane wings go up or down. The pilot turns the ailerons by turning the wheel right or left. |
|
|
Yaw |
The plane turns right or left. The pilot uses foot pedals and if she/he pushes down the left pedal the plane goes right, also if she/he pushes down the right pedal the plane goes left. |
|
|
Thrust |
The pilot pushes the throttle forward to move faster and pulls it back to go slower. Similar to a jet engine and propeller. |
|
|
Lift |
To move up in air. The pilot controls the flaps. |
|
|
Pressure |
A force against an object. |
|
|
Fluid |
Something that flows easy, and takes the shape of its container. |
|
|
Ailerons |
The flaps on the wings that control roll. |
|
|
Rudder |
The flap on the vertical stabilizer that controls yaw. |
|
|
Elevators |
The flaps on the horizontal stabilizer that control pitch. |
|
|
Drag |
How much air resistance something has. |
|
|
Bernoulli's Principle |
The wind on the top of the wing is moving faster than the wind below the wing so the plane is forced upward which is lift. |
|
|
Helium |
A gas that is lighter than air. |
|
|
Lighter than air |
Helium, anything that floats in the air. |
|
|
Stationary |
To not move and stand still. |
|
|
Gravity |
A force that pulls you toward the earth. |
|
|
Aerodynamic |
Something shaped to cut through the air easily when it’s moving. |
|
|
Contracion |
When something becomes either smaller, shorter or tighter. |
|
|
Expansion |
To get bigger or enlarge. |
|
|
Spacecraft |
A vehicle used for traveling in space. |
|
|
Aircraft |
A airplane, helicopter, or other machine capable of flight. |
|
|
Propulsion |
A force that pushes an object forward. |
|

Properties of fluids |
1. Air Flows 2. Air Takes up space 3. Air is a fluid 4. Hot Fluids are less dense 5. Cold Fluids Contract 6. Hot air takes up more space 7. Cold air takes up less space 8. Fluids take shape of the container they're in. 9. Air can exert pressure 10. Hot Fluids expand 11. Cold Air are more dense |

Bernoulli's Principle Experiment |
Blow a stream of air through a paper tent see what happens, than blow harder and observe. observation: The sides come closer together. |
